Answer:
Please read explanation below.
Step-by-step explanation:
Let's go over what some of the symbols of inequalities represent:
: greater than
: less than
: greater than or equal to
: less than or equal to
The symbol in the equation that is given to you is . It seems as though each of the answer choices have everything written as the same thing except for the description of the inequalities. Check the one that applies.
For the first part, the answer is choice B) 360. This applies to any polygon and it doesn't have to be an octagon. The sum of the exterior angles of any polygon is always 360 degrees. This is something you should memorize or have on a reference sheet.
For the second part, the answer is choice C) 142 degrees. We have a parallelogram (specifically a rhombus but that doesn't matter) so the adjacent angles are supplementary. This means they add to 180 degrees. Solving x+38 = 180 leads to x = 142
Answer:
x=−7
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
The discontinuities are x=-4. Because it is a fraction, you cannot divide by zero so if the denominator is set to equal zero, which it will if x=-4, the function will be be undefined
Answer:
Option A. 
Step-by-step explanation:
step 1
Find the volume of the sphere ( medicine ball)
The volume is equal to
we have
----> the radius is half the diameter
Convert inches to feet
Remember that
1 ft=12 in
assume
substitute
step 2
Find the weight of the ball
Multiply the volume in cubic foot by 100
Round to the nearest pound
